1. What is the Holliday-Segar Formula?

The Holliday-Segar formula is a method for calculating maintenance intravenous fluid requirements in pediatric patients. It provides a standardized approach to ensure adequate hydration while preventing fluid overload.

2. How Does the Calculator Work?

The calculator uses the Holliday-Segar formula:

\[ mL/hr = 4 \times Weight (kg) \text{ for first 10 kg} + 2 \times \text{(next 10 kg)} + 1 \times \text{(rest)} \]

Where:

\( Weight \) — Patient weight in kilograms
\( 4 \times Weight \) — For the first 10 kg of body weight
\( 2 \times (next 10 kg) \) — For weight between 11-20 kg
\( 1 \times (rest) \) — For each additional kg above 20 kg

Explanation: This formula accounts for the higher metabolic rate and fluid requirements per body weight in smaller children compared to larger children and adults.

3. Importance of IV Fluid Maintenance

Details: Proper fluid maintenance is essential for maintaining hydration, electrolyte balance, and supporting vital organ function. Accurate calculation prevents both dehydration and fluid overload complications.

4. Using the Calculator

Tips: Enter the patient's weight in kilograms. Ensure accurate weight measurement for precise calculation. The calculator automatically applies the appropriate formula based on weight category.

5. Frequently Asked Questions (FAQ)

Q1: What age group is this formula designed for?
A: The Holliday-Segar formula is primarily used for pediatric patients from infancy through adolescence.

Q2: Are there any contraindications for using this formula?
A: Yes, this formula may need adjustment in patients with renal impairment, heart failure, sepsis, or other conditions affecting fluid balance.

Q3: How often should maintenance fluids be recalculated?
A: Fluid requirements should be reassessed daily or whenever there are significant changes in clinical status or weight.

Q4: Does this include replacement for ongoing losses?
A: No, this calculation provides maintenance fluids only. Additional fluids may be needed for ongoing losses from vomiting, diarrhea, or fever.

Q5: What about electrolyte replacement in maintenance fluids?
A: Maintenance fluids typically include electrolytes (sodium, potassium) in addition to the calculated water volume.
